As @Rezzagan#77802 misunderstood what I meant, I will try to clarify. Apologies for the confusion.
I cast Amped Raptor, gain 2 energy. I exile cards from the top until I exile wrath of the skies. I decide to cast wrath of the skies.
I choose the cost of x = 0, paying 2 energy to do so, as Amped Raptor requires.
Then, Wrath of the Skies resolves.
I choose to pay 0 energy, which should destroy all relevant permanents with mana value 0.
However, it destroys permanents with mana value 2 or less, mistakenly including the energy paid through the raptor's ability.
